CUTTING AND PUNCHING MACHINE.

To aZZwiwm it mag concern:

Be it known that I, MICHAEL J. SALvioLo, a citizen of the United States,and resident of Brooklyn, Kingscounty New York, and executor of theestate of 6 wow, late a citizen of the United States, and resident ofBrooklyn, Kings county, New York, declare that the said UARMINE J. SAL-VIOLO has invented a new and useful Improvement in Cutting and Punch1ngMachines, of which the followlng 1s a specification. 7

This invention relates to cutting and punching machines and moreespeclally'to portable machines adapted to carry a roll of metal tape,theend of which is fed into the machine automatically and beneath one ormore punches where perforations are made having spurs around thelr edgesand the tape is then fed beneath a knife and plunger and a strip is cutoff and aflixed to a card or board beneath the device, the object of theinvention being, to secure a str1p of sheet metal to a box to supportcertam goods being shipped therein or for similar purposes. Y

invention are more fully described in the following specification, setforth in the appended claims and illustrated 1n the accompanyingdrawings, where n:

Figure 1 is an elevatlon of the devlce partly in section,

Fig. 2 is a front view of the cutter and puncher,

Fig. 3 is an enlarged view of the knife. Fig. 4 is a plan view of astrip produced by the machine.

The device comprises a casmg 5, inclosmg a plunger 6, at whose upper endis a stem 7, and the extremity of the latter has secured to it thehandle 8, and it isencircled by a sleeve 9, with flange 10 and presseddownward by the spring 11, to engage the top of the casing 5, and act asa buffer as the plunger reaches its downward limit.

The lower end of the plunger 6, carries a hard steel knife blade 12,which is rounded slightly at 13, on its front edge to cause a deflection14, in the metal strip as Wlll be seen in Figs. 3 and 4, but it isevident that other forms may be used, if needed.

The plunger also has secured to its face near the lower end a block 15,that carries Specification of Letters Patent. l

above the block is whose function will be Guides 18, at each side of thecasing serve to retain the plunger and carried by an arm 19, from oneside of the casing is the spool 20, adapted to freely rotate on thespindle 21, and carry a long strip of sheet metal.

W hen the latter leaves the spool, it passes beneath the cam roller 22,held open by means of the spring 23, and arm 24, and is'journaled in aframe 25, hinged in brackets 26, and having a knob 27, 011 its innerface and adapted to be struck by the cam 17 and the whole swung towardthe spool '20. The gripping effect of the roller 22, is relaxed in thisupward movement and an appropriate amount of the metal is received intothe frame which is immediately drawn forward as the plunger is elevatedand, by springs 28, at each side of the frame and casing and thefriction consequent of the rasping surface of roller 22, causes it toclose down upon the sheet metal and draw it from tl. e spool.

The outer end of the metal strip, which is shown in Fig. 1, by dottedlines, is supported These and other objects and details of the by asmall yielding platform 29, and adjacent the same is the die 30, withperforations 31, through which the punches 16, play and it is duringthis play that the sleeve 9, and spring 11, come into action.

The metalstrip passes into channels 32, in the guide ways 26 and lodgesagainst the rear wall of the casing where it is supported by the ballbearing 33, made yielding by the confined spring 34, to gage 35, whichis located at the rear of the device and may be used to properly locatethe same with relation to an edge in the cardboard or neighboring stripswhile lateral gagesv 36, may be used for the same purpose.

In operation, the metal tape before entering the casing and locatingbelow the plunger first receives its perforations from the puncher andthe forward edge is cut off by the knife. lVhen the plunger is elevatedthe cam 17, is withdrawn from the path of the knob 27, and the framemoves into the normal position shown in Fig. l and at the same timefeeds the tape forward so that the perforations are now beneath theplunger and the blank beneath the punches and the former is out off bythe blade and the prongs are driven through the card board I PatentedJuly 5, 1921.

and, when done on a metal table, clenched on the lower side of same.

The platform 29, plays at each end against lateral pins 37, and clampsthe metal strip therein and holds it when the frame 25, is swungoutward, but the force of springs 28, overcome this pressure and feedthe strip forward as its end is out off.

It is obvious that the parts may be otherwise arranged and modifiedwithout depart-. ing from the essential features above described.

What I claim as new is 1. In a cutting and punching apparatus, thecombination of a casing containing a plunger, punches carried by theplunger at its lower end, a cutting blade adjacent the punches, meansfor feeding a strip of sheet metal, and means forming a part of theplunger for operating the feeding means. as the plunger descends.

2. In a cutting and punching apparatus, the combination of a casing, aplunger adapted to play in the casing, punches and a blade at the lowerendof. the plunger, an oscillating frame in'the path of the plunger, acam in theframeand adapted to grip and feed a strip of sheet metal, andmeans connected with the plunger for oscillating the frame and freeingthe strip.

3. In a cutting and punching apparatus, the combination of a casinghaving guide ways, a plunger working in the guide ways, a knife blade atthe lower edge of the plunger, a punch at the lower end of the plunger,a spool for a sheet metal tape, a swinging frame at the lower end of thecasing, a knob on the, frame and in the path of the plunger, meansconnected with the frame for feeding the tape beneath the plunger, andyielding means for supporting the outer end of the tape. I

l. In a cutting and punching apparatus, the combination of a casinghaving guide ways, a. plunger, with a yielding handle and playing in theguide ways, a cam on the plunger, a. swinging frame with a knob adapted.to be struck by the cam and tilted, a cam in the. frame and adapted togrip a tape, a knife blade and punch carried by the plunger, grippingmeans for the end of the tape, and yielding supporting means for thesame.
